View Full Version : Simulation Software

Okay, I'm trying to figure out G-Code on the sly, since my supervisor Pete Puma (http://bbs.homeshopmachinist.net//Forum1/HTML/008330.html), has basically been given an assignment, which is akin to peeing in a corner in a round room. http://bbs.homeshopmachinist.net//biggrin.gif He'll still be around the shop, so it'll be difficult for me to check my code in the simulator on the CNC at work, thus I need some kind of software I can run at home that'll tell me if I've written or rewritten the program right (I've managed to copy all the programs we've got at work on the sly, so it'll be easy for me to tinker with them at home, and then bring them to work and load them while Pete's busy). Anybody know of anything?

You will need to boot to DOS to use this.

So how do I do that on a machine running XP Pro? (I've got a box I can roll back to 98SE, if that's easier.)

On XP, go to the start menu and select
"RUN", when the run box pops up type in

CMD and hit return. That will bring up
a DOS window.

A DOS box on XP won't work. The Hardware Abstraction Layer prevents direct access to IO registers.

Never mind, try this one.

I use Ah-Ha on my Bridgeport. You could run a duel boot or just a simple boot disk. You want it to be pared down to nothing. No extra drivers such as sound, CD or anything that Dos does not need. Mouse, yes. For the boot disk to work you will need to "install" dos because Win XP does not use the same command file. Boot disks used to be a snap with win 95/98 cause they still used the command files.

Try looking at the yahoo group for ahha and do a search for configuring a computer for dual boot, I think I remember somethin in the past. AHHA has a nice feel to it, should be fun and the demo is free.

I can't remember what the limitations are for the demo, funny, it might be importing G-code.

The limitation on the AHHA demo is it won't actually run your machine.

I'm not sure I fully understand your requirements, but if you just want to backplot G-code programs you've brought home from work or written yourself, this freebie (Discriminator) works fine:

If you want help in learning to write programs and viewing the results of your efforts interactively, there's a nice free program at:


It comes with an offer for a book, but you don't have to buy the book.

Well, I've piddled around with all of the programs and gotten a couple of them to work, sort of. Obviously I'm going to have to break down and read the help files on them, because in simply running a program I'm well familiar with, the display either shows me something which doesn't make any sense, or it makes cuts in the wrong spot, since I can't figure out how to get it to set the zero points where they need to be.
